Question

Find the equation of a straight line parallel to x-axis which is at a distance.
(i) 2 units above it
(ii) 3 units below it

Answer 1

(i)two units above x-axis $\Rightarrow$ passes through $(0,2)$

$\therefore y=2$.

(ii)three units below x-axis $\Rightarrow$ passes through $(0,-3)$

$\therefore y=-3$
